Not all schools provides email addresses to their students, and some students will just decide not to use them... why?, well, because, after all, these are temporary address, for as long as you are at the school, you can't keep those for the rest of your life, and thus some students decide not to use them. >> >> If someone does not have a valid email address at a reasonable domain then >> we don't want to hear from them anyways. > > Yes, but you're not selling anything or providing any kind of public > service. So it doesn't matter if people can't email you. Those of us who > work for commercial organisations or government bodies don't have that > choice. Same here, that's exactly why I don't use a "hard" block policy, I use scoring (with ASSP) and even use Bayes filters (yeah, those that requires "training" and stuff), thanks to this combination I get rid of ~95% of the spam, while keeping over 99% of good mail (I almost never lose a legit mail because of the mail filter). yahoo, hotmail, gmail are domains used by all kind of persons (I have even seen customers that just uses companyn...@gmail.com as their corporate mail!!), so: just blocking them because a few send spam is non-sense.... you need to check message content, that's why I use Bayes as part of the scoring. Now, spam fight is everyday harder, because spammers are looking everyday more like legitimate senders... as a matter of fact, sometimes what I consider spam is not considered spam by other person, so... this is actually a complex topic.
